| 摘 要： | 以红花银桦（Grevillea banksii）为材料,选取了不同区域进行试验,栽培10个月后对红花银桦叶片氟、硫含量进行了测定,同步测定了大气氟、硫含量。结果表明,两试验点大气氟含量均低于国家二级标准,但两试验点大气存在一定程度二氧化硫污染,五星点最高超过国家二级标准达11倍多。不同区域植物叶片氟、硫含量有明显的差异,叶片氟、硫累积量与大气中氟、硫含量存在密切相关性;而植株生长正常,说明红花银桦对二氧化硫污染的大气具有较强的忍耐和抵抗能力,同时具有较强吸收净化氟化物、硫化物的能力。

| Abstract: | Seedlings of Grevillea banksii were planted in two districts-Wuxindian and Yunyong forest center for 10 months and concentrations of fluoride and sulfur were detected in the air and on the leaves of Grevillea banksii to probe its tolerance to air fluoride and sulfur pollution.The results showed that the conentration of air fluoride of the two districts were lower than the national standard grade two,while air of Wuxidian and Yunyong was polluted by sulfur and air sulfur concnetration of Wuxidian was found t... |
